Use your microwave. It cooks faster and uses far less electricity than your electric oven.

When using your regular oven, it helps to cook several dishes at the same time and therefore at the same temperature. Don't open the door to see how things are going. Just opening the door will drop the temperature significantly.

Glass pans retain heat better than metal pans. With glass you can reduce preheating times and lower the temperature setting by 5 percent.

On the range-top, use pots and pans that have flat bottoms and that fit the burner. Cook with lids on the pans to shorten cooking time.
